Any commentary that the FAA receives that is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background The FAA issued AD 2026-13-05, Amendment 39-23387 (91 FR 39854, July 1, 2026) (AD 2026-13-05), for all The Boeing Company Model 737-8, 737-9, and 737-8200 airplanes. AD 2026-13-05 required revising the existing AFM to provide the flightcrew with operating procedures (non-normal checklists) if a certain circuit breaker in the SPCU trips or certain ECS circuit breakers downstream of the SPCU trip. AD 2026-13-05 was prompted by reports of in-flight events of excessive cabin and flight deck temperatures that could not be controlled by the flightcrew using existing procedures. The FAA issued AD 2026-13-05 to address a tripped BAT BUS SECT 2 or ECS circuit breaker that could lead to an air conditioning system malfunction causing an uncontrollable, excessively high temperature in the cabin and flight deck. The unsafe condition, if not addressed, could lead to injury or incapacitation of flightcrew and passengers, which could result in the inability to maintain safe flight and landing. Actions Since AD 2026-13-05 Was Issued Since the FAA issued AD 2026-13-05, it was discovered that there is a formatting error in appendix 5 of AD 2026-13-05 that omitted steps 1 through 8 of the Cabin Temperature Hot PACK CONT VALVES RIGHT or LEFT Circuit Breaker Trips procedure. FAA's Determination The FAA is issuing this AD because the agency has determined the unsafe condition described previously is likely to exist or develop in other products of the same type design. AD Requirements This AD retains certain requirements of AD 2026-13-05. This AD also requires revising the existing AFM to include the corrected appendix 5 to provide the flightcrew with the Cabin Temperature Hot PACK CONT VALVES RIGHT or LEFT Circuit Breaker Trips procedure. Interim Action The FAA considers this AD to be an interim action. The manufacturer is currently developing a modification to address the unsafe condition identified in this AD. Once this modification is developed, FAA-approved, and available, the FAA might consider additional rulemaking. Justification for Immediate Adoption and Determination of the Effective Date Section 553(b) of the Administrative Procedure Act (APA) (5 U.S.C. 551 et seq. ) authorizes agencies to dispense with notice and comment procedures for rules when the agency, for "good cause," finds that those procedures are "impracticable, unnecessary, or contrary to the public interest." Under this section, an agency, upon finding good cause, may issue a final rule without providing notice and seeking comment prior to issuance. Further, section 553(d) of the APA authorizes agencies to make rules effective in less than thirty days, upon a finding of good cause. An unsafe condition exists that requires the immediate adoption of this AD without providing an opportunity for public comments prior to adoption. The FAA has found that the risk to the flying public justifies forgoing notice and comment prior to adoption of this rule because a tripped BAT BUS SECT 2 or ECS circuit breaker, and resulting effects on the cabin environment that cannot be controlled via normal procedures, could lead to injury or incapacitation of flightcrew and passengers, which could result in the inability to maintain safe flight and landing. Additionally, the compliance time in this AD is shorter than the time necessary for the public to comment and for publication of the final rule. Accordingly, notice and opportunity for prior public comment are impracticable and contrary to the public interest pursuant to 5 U.S.C. 553(b). In addition, the FAA finds that good cause exists pursuant to 5 U.S.C. 553(d) for making this amendment effective in less than 30 days, for the same reasons the FAA found good cause to forgo notice and comment. Regulatory Flexibility Act The requirements of the Regulatory Flexibility Act (RFA) do not apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and comment. Because the FAA has determined that it has good cause to adopt this rule without notice and comment, RFA analysis is not required. Costs of Compliance The FAA estimates that this AD affects 825 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD: Estimated Costs Action Labor cost Parts cost Cost per product Cost on U.S. operators AFM Revision (retained actions from AD 2026-13-05) 1 work-hour × $85 per hour = $85 $0 $85 $70,125 AFM Revision (new AD action) 1 work-hour × $85 per hour = $85 0 85 70,125 Authority for This Rulemaking Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. Subtitle VII: Aviation Programs describes in more detail the scope of the Agency's authority. The FAA is issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701: General requirements. Under that section, Congress charges the FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action. Regulatory Findings This AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government. For the reasons discussed above, I certify that this AD: (1) Is not a "significant regulatory action" under Executive Order 12866, and (2) Will not affect intrastate aviation in Alaska. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39-AIRWORTHINESS DIRECTIVES 1.
